Last week we discussed some concepts of GCF. Today we will talk about GCF and LCM of fractions.
LCM of two or more fractions is given by: LCM of numerators/GCF of denominators
GCF of two or more fractions is given by: GCF of numerators/LCM of denominators
Why do we calculate LCM and GCF of fractions in this way? Let’s look at the algebraic explanation first. Then we will look at a more intuitive reason.
